Our testing services include basic wear, abrasion and friction test configurations: - Pin-on-Disk (ASTM G99) - Linear Reciprocating (ASTM G133) - Ball on Flat - Flat on Flat Wear and abrasion test setup can be customized to meet customer's application. The pin-on-disk technique creates a circular wear track by spinning the sample. With the linear reciprocating technique, the sample is moved back and forth to create a wear track in the shape of a straight line. Both test configurations can be used to measure the dynamic (kinetic) coefficient of friction with and without wear.
